RapidAPI co-founder raises $15 million for AI marketing startup enso
Mickey Haslavsky’s company has raised $23 million to build what it calls “Agentic Growth Hacking.”
Israeli startup enso, which develops AI agent systems for marketing and sales, has raised $15 million in a Series A round led by MoreTech Ventures, with participation from existing investor NFX, Phenomen VC, and Gil Hirsch. The round brings the company’s total funding to $23 million.
The new capital will be used to expand enso’s operations in what the company calls “Agentic Growth Hacking,” as businesses increasingly rely on AI tools to reach customers.
The way companies reach customers is changing rapidly. Search algorithms, social media feeds and AI answer engines increasingly determine which businesses and products users encounter. Consumers and businesses are also turning to tools such as ChatGPT, Claude, Perplexity and Google AI Overviews to research companies and products alongside traditional search engines and social networks.
That creates a moving target for marketers. Strategies that work today can lose their effectiveness as platforms change their algorithms, recommendation systems and rules, while user behavior evolves.
Enso’s AI agents analyze how different platforms rank, recommend and cite content. They then test different approaches through small-scale experiments and measure the results. When an approach proves effective, enso can turn it into a repeatable growth mechanism for a customer. Tactics that stop working can be retested or abandoned.
The company currently works with enterprises and startups including Papaya Global, MyHeritage, Papaya Gaming, Natural Intelligence, Winn AI and Israel Canada.
For each customer, enso embeds an engineer and a marketer who connect the research to the company’s existing sales and marketing operations, systems and brand. The team builds a set of agents around those workflows and measures their performance against an established business and pipeline baseline.
The systems operate across several channels, including search and AI-answer visibility, sales outreach, online communities, newsletters and social media. In AI search, for example, enso tracks which companies and sources are cited in answers to relevant questions and measures whether changes in content and distribution affect a customer’s visibility.
Human oversight remains part of the system. Marketers determine strategy, brand boundaries and which playbooks are deployed, while the agents handle ongoing monitoring, testing and execution. Sensitive or irreversible actions remain under human control.
Enso was founded in 2024 by Mickey Haslavsky, who serves as CEO and previously co-founded RapidAPI. Haslavsky coined the term “Agentic Growth Hacking” and is writing a book under the same title.
The company employs 26 people, most of them based in Israel. enso publishes research on its experiments, including unsuccessful ones and the lessons learned from them, and maintains open-source reference skills for AI agents.
“Marketing teams can spend months building a strategy around channels that change before they see results,” Haslavsky said. “AI agents make it possible to monitor multiple platforms continuously, test where opportunities are emerging and act while those opportunities still matter. We embed an engineer and a marketer with the customer, build the system around how they operate, measure against a baseline and keep a person accountable for what the agents do.”
